Method for producing composite elements m the hmm of foa?ued material teed ο» isocyanate
The invention relates to a prodës&fëi' pÄmi&g eonfoosie elements &0m at least one covering layer and a foam·forming reaction mixmrn which is applied by means of a Used easting bar to the lower covering layer.
The production of composite elements comprising, in partiadat, metallic covering layers and a core of foams based on isocyanate, usually polyurethane (PUR) or polyiscwyauurate (P® foams, foeipeutly also referred to as sandwich elements, on continuously operating double: belt uhlfe is at present carried ont on a large scale. Apart from sandwich: elements for insulation of refrigerated rooms, these elements are becoming increasingly important for the construction of facades of a wide variety of beddings. As covering layers, use is made of coated steel sheets and also stainless steel, copper or aluminum sheets, i^rbculMly in the ease of façade elemmtfe, the surface structure of the foam boundary to the eovenng layer plays a critical role. Por a wide variety of reasons, undesirable air inclusions between the lower covering layer and tlm foam based on isocyanates, known as voids, often occur In the production of the sandwich eiemcnis. These air inclusions between the nmml sheet and foam can lead,: particularly in the ease of large temperature changes and dark colors of the covering layer when the elements are used as fopde elements, lead to humps in the metal sheet and spoil the: appearavtce of the façadm
Ptnthermöre, the adhesion between insulating;; foam and lower covering layer is :redeeed If: is often the case that the lower covering layer in sandwich elements displays the foorest adhesion, determined in a tensile test. Furthermore, the: metal sheet on. ite underside forms the outs ide of the hfoade m the usuel constructions produced by means of sandwich elements, so that it is exposed to extreme conditions: such as temperature and; suction ami ts thereto? e subject to greater stress than the upper side of the sandwich element, winch can lead to detachment of the foam from the metainsheet: and thus likewise to bumps.
It is therefore necessary to find a process which; lastingly unmmmes or completely avoids void íonnadon; at the surface of tie rigid ifoähts feasefi oß Isocyanate and also works in the case of adverse d^tériiâf condi tions in the production pfoeëss, Thu process: should he able to be: used continuously of diseontlnuonsly. À discontinuons procedure can, for example, come bbo question during start-up of the double belt and in the case of composite elements produced by means of discontinuous pressing, The process is carried out continuously when double béli units are used, as disclosed in WO 2()05/01:1950 A2,
In the case of (he double belt process according to the pior art, dm reaction mixture is produced by machine using the high- or low-pressure technique and is applied by means of oscillating casting bars to the lower covering layer- Here, the casting bar is aligned In the direction of movement of the beit and oscillates across the width of the element, A disadvantage of this method of application is that void formation on the upper side cannot be avoided completely, since air hubbies are always formed In the reaction ndpufe due to the manner of application, This· 4isadiv«agn':tenM^:fr^fer the shorter die time between application of the reaction mixture and commencement of fhe foaming reaction. The velocity of the continuously operating double belt is limited by the maximum possible oscillation speed of the mixing, head. An additional disadvantage is that as oscillation increases, pore reaction mixture is applied in the edge region and less in the middle region of the covering layer.
In an alternative rapid process, the reaction mixture Ί& applied by ntultifinger application to the lower covering lap?, and in this case too, air bubbles are included: In :the reaction mixture and only surfaces suffering ifom voids earn like whe be produced, In addition, in this method of application, the reaction mixture has to spread sideways over relatively large regions so that relatively large voidyrones are formed on the lower Pid tippe?: covering layer, especially in the oufommst regions before: the individual shrams of the multifinger application flow into one another. Fiuthermore, there is ffoqnently a furrow or at least n foam, defect: visible in the region in which the streams of the muldringer application flow into one another, 1¾ alienate this delect, DE 19? 41 523 proposes blowing air onto the: still fiowafbe foam mixture aÉçr application of the liquid reaction mixture for the rigid foam to the covering layer. This is said to smooth the surface of the reaction mixture and reduce the inclusion of air bubbles. A disadvantage of this procedure is, firstly, that the blowing-on of air represents an additional process step. Secondly, Ée stream of air can lead to banking-up of the reaction mixture, which likewise causes an kmpiar surface.
It. was an object of the present invention to discover a process for applying a reaction mixture for a rigid foam based on isocyanate. In particular a FflE or PIR system, to a horixontal metal sheet or another Sexible or rigid covering: layer which is imnsported continuously in a horizontal direction as is customary for production of sandwich elements using; a continuously operating double belt, The process should give a surface structure of the foam on the lower covering layer which is improved compared to the prior art and, m particular, lead; to avoidance of voids. Imrthefmore, the process should lead to improved adhesion between covering layer and rigid1 foam, in particular, the surface of the applied foam should be uniform. The process should, in particular, he suitable for fast-cmamlng; systems and the aboyemsatloned: disadvantages of nmltlfioger application and of oscillating casting bar application should |e avoided.
This object has surprisingly been able to he achieved by the reaction mixture being applied to the lower covering layer by means of a fixed tube which is provided with orifices and is arranged parallel to the covering layer a) and at right angles to the direction of movement of the covering layer φ, hereinafter also mferred to as easting bar.
The Invention accordingly provides a process for producing composite bodies comprising at least one covering layer a) and a rigid foam based m isocyanate h), in which the covering layer a) is moved continuously and the starting material for the rigid foam based on isocyanate bj is applied to the covering layer and the application of the liquid starting material; for the rigid foam based on isocyanate hi is ettocted by means of a fixed tube which is provided with orifices and is arranged parallel to the coveting layer a) and at right angles to the <irecöQn: of movement of the covering layer a), wherein the liquid starting material lor fee rigid foaxn based on isocyanate b) Is fed m.

The easting bar Is tonally arranged at a height of from ID to 30 cm, preferably from IS to 25 cár, from the lower covering layer.
The diameter of the tube decreases from the rniddfo: to the ends of the tube. Furthermore, the diameter of fee outlet holes and/or fee spacing of the holes can be reduced from fee middle to fee ends of fee casting bar. These measures, which can be implemented either afone or In combination with one another, are intended to keep the velocity of the reaction mixture in the tube or on exiting the holes constant.
The length of foe tóbe ©an te equal to íte width of the covering layer a).. Tüte length of Öté tube is preferably smaller than the width of the covering layer a) in order to ensure that, the reaction mixture Is not partly applied next to the covering layer. The casting bar is arranged centrally above the covering: layer a).

The foam surface obtained in this way was illuminated at an included angle of 5° and the area of the shadow thrown by surface defects was divided by the total surface area. For this purpose, the illuminated foam surface was plmfegräphed and the: foam images were subsequently binarized. The integrated area of fee black regions of the binary images was divided by the total area of the images and thus represents a nmaaure of the frequency of surface defects, fferthenUore, an additional qualitative assessment: of fee nature of the surface of the foatm was carried out by removing the covering layer from a I: m x2 m foam specimen and visually assessing the surface.
The various experiments using different rigid foam systems and an osciHafiog and fixed casting bar are compared in Table !.
C - Comparative example liable 1. Experimental parameters and results, lire uniformity of the applied layer over the surface of the covering; layer is assessed;.. 'the results in Table 1 show that the frequency of the formation of surface defects at the interface to the metallic covering: layers is significantly reduced by the use of the fixed easting bar Compared to the pier art and the mechanical properties of the foam and also the adhesion between rigid fbaur and covering layer are improved.
